Sims 4 can wait for me, I'll still play Sims 3 until I can afford another super computer and need loads more money to afford both, so Sims 3 is gonna be played for another 4yrs by me.
If Sims 4 had the (create a pattern) in the game like TS3 has got and more sliders, pimples and dimples etc, scars and scratches etc, and more animation of hair flow and wind flow thru the windows, abilty to open and close windows/curtains etc, ability to mow the lawn when the grass grows, option to recolour roofs, the animation and graphics needs to WOW me over to get Sims 4 when it's released, I highly doubt this will happen yet! :)
